Parker 387-8-RL Hydraulic Hose 3000 Psi 1/2 Inch Id

Product Description

The PARKER 387-8-RL is a -8 hose size hydraulic hose built for high-pressure fluid transfer in mobile and industrial hydraulic systems. It features a 1/2 inch inner diameter and a 0.82 inch outer diameter, with a rated working pressure of 3,000 psi. The hose is constructed from synthetic rubber, providing flexibility and resistance across a wide temperature range of -40 degrees F to 212 degrees F. A 3.5 inch minimum bend radius supports routing in tight equipment spaces. This hose is installed by hydraulic technicians, fluid power mechanics, and heavy equipment service professionals.

The 387-8-RL suits a broad range of hydraulic applications including agricultural equipment, construction machinery, industrial presses, and mobile equipment platforms. The -8 hose size is a standard designation in SAE hydraulic hose sizing, making it compatible with common end fittings and adapters used across the trade. Its synthetic rubber construction handles petroleum-based hydraulic fluids found in most mobile and stationary hydraulic systems. This hose is sold by the length and is a stocking item for shops that regularly service mid-pressure hydraulic circuits.

Key Features

• 3,000 psi working pressure rated for mid-to-high pressure hydraulic circuits
• 1/2 inch ID bore sized to the standard -8 hose designation
• Synthetic rubber construction compatible with petroleum-based hydraulic fluids
• Operating temperature range of -40 degrees F to 212 degrees F
• 3.5 inch minimum bend radius allows routing in confined equipment compartments
• Black outer jacket for standard field identification

Compatibility

Designed as an OEM-style replacement or new-installation hose for hydraulic systems requiring a -8 hose size at up to 3,000 psi working pressure with standard SAE end fitting connections.

Installation Notes

Hydraulic hose assembly and installation should be performed by a qualified fluid power technician or hydraulic mechanic. Always relieve system pressure completely before disconnecting or replacing any hydraulic hose. Do not exceed the rated working pressure of 3,000 psi, and observe the minimum bend radius of 3.5 inches to prevent internal liner damage and premature failure. Follow applicable SAE and machine manufacturer specifications when selecting and torquing end fittings.
